Abstract

La présente invention concerne des procédés et des appareils de configuration et de transmission de signaux d'économie de puissance. Selon la présente invention, une station de base configure des informations de configuration d'ensemble d'espaces de recherche d'un signal d'économie de puissance, et les envoie à un terminal. Les informations de configuration d'ensemble d'espaces de recherche de signaux d'économie de puissance comprennent des premières informations de configuration et des deuxièmes informations de configuration ; les premières informations de configuration sont des informations de configuration d'ensemble d'espaces de recherche d'un signal d'économie de puissance utilisé lorsque le terminal est dans un cycle de DRX court ; et les deuxièmes informations de configuration sont des informations de configuration d'ensemble d'espaces de recherche d'un signal d'économie de puissance utilisé lorsque le terminal est dans un cycle de DRX long.
